Australia. We only have 6 states and 2 territories but apparently we are the “largest island and smallest continent” in the world. I know they’ve done maps where they’ve fit tonnes of other countries into ours from Europe and other places… we don’t have many people but we’re not a small country.

Edit I just found that Australia is approximately 7,741,220 sq km and the US is approximately 9,833,517 sq km but you have 307.2million more people living there. I can’t imagine that many people! Sorry going off on a tangent here I just find it interesting.
